Explanation:

To calculate the concentration of the paracetamol solution, <em>C</em>, in terms of mg/mL, using dimensional analysis, we can derive the following relation shown below

                                C \ = \ \displaystyle\frac{\text{mass of paracetamol tablet \ \ (mg)}}{\text{volume of solvent \ \ (mL)}}.

Therefore,

                                                         C \ = \ \displaystyle\frac{100 \ \text{mg}}{100 \ \text{mL}} \\ \\ C \ = \ 1 \ \text{mg ml}^{-1}.

Studentka2010 [4]

Answer:

d. cell membranes

Explanation:

The movement of the the fluid is  a combination of both the osmotic and the hydrostatic pressures.

Osmotic pressure results from the differences in the solute concentrations across the cell membranes. On the other hand, hydrostatic pressure results from pressure of the blood as it enters the capillary system, forcing some amount of the fluid out of vessel into surrounding tissues.

<u>As a result of these factors, the fluid movement occurs through cell membrane.</u>

What body systems are dependent onthe respiratory system.
dem82 [27]

Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles.
